The generation of TTC values based on (Q)SAR is at this stage, where NOAEL prediction is hardly possible, not foreseeable.
Fortunately, the NOAEL example appears to have no analogue in natural hazards risk assessment.

Therefore, the NOAEL for the sub-chronic 28-day study was determined to be 2000 mg/kg bodyweight/day, the highest close tested.
Chronic toxicity studies identify an additional reference point on the dose-response curve, known as the threshold or no observable adverse effect level--NOEL or NOAEL.
For arsine, a NOAEL was identified in mice exposed to 500 ppb for one hour; this was the lowest concentration tested (10).
In the present study, it was necessary to administer oral doses that were many orders of magnitude lower than the NOAEL to observe urinary metabolite concentrations that were within the ranges reported for the U.
